as explained in the title my fuse has blown twice for the 12v sockets... first time i thought nothing of it but i haven't plugged nothing in the socket for a while and when i went to charge my phone the other day found them not to be working again?!?

im not 100% what size fuse is in there but im sure it meets the recomendations... could it be worth increasing the fuse size or is that dangerous...

its a stupid question i know but its late and ive had a long day lolol
